On April 26,1986 at 1:24am, a rainbow-colored flame shot 1,000 meters high into the Ukrainian sky. The fourth reactor at the Chernobyl nuclear power plant had just exploded. The battle of Chernobyl had begun. For eight months, 800,000 young soldiers, miners and even civilians from all corners of the Soviet Union worked to try and "liquidate" the radioactivity, build a "sarcophagus" around the ruined reactor, and above all, to save the world from a second explosion. Provoked by a terrific chain reaction, a second nuclear explosion ten times more powerful than Hiroshima, threatened at any moment to wipe out not only the entire Ukraine, but half of Europe as well. It was a race against the clock that the first participants in the battle of Chernobyl aren't about to forgot. This documentary uses personal accounts as well as archival footage and documents to recreate the events of the great battle of Chernobyl day-by-day, as each development unfolded.
